MAIN FEATURES
The KICKER KEY 200W 4-Channel Smart Amplifier with Plug 'n' Play ISO combines powerful amplification with automatic sound optimisation for a simple and effective audio upgrade. Delivering 50W x 4 at 4 ohms, the KEY200.4 uses advanced signal processing to optimise the sound specifically for your vehicle's interior.
The included calibration microphone allows the KEY Auto Setup software to automatically configure the 40-band EQ, crossover settings, speaker size and time alignment for the front-seat listening position. The microphone selector switch also lets you compare the original sound with the processed setup.
This version includes a universal ISO plug-and-play harness for easier installation without the need for complicated wiring. FIT2™ technology provides compatibility with nearly every factory and aftermarket radio, while start/stop compatibility makes it suitable for modern vehicles. Its compact design allows flexible mounting behind the radio, under a seat or in the boot.
